UNITED STATES PATENT OFFICE.

FRITZ GEORGE HOBERG, or wooNsooKET, RHODE ISLAND,

MACHINE r03. AUTOMATICALLY AssE BLINGwI'R HEDDLESI.

Be it known that I, F Rrrz GEORGE HOBERG, citizen of the United States, residing at W oonsocket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Machines for Automatically Assembling Wire Heddles', of which the following is a specification. I

The usual method practised in assembling wire heddles with the cross bars of a heddleframe, used in looms, is for girl operatives to thread or string said heddles onsaid cross bars, by hand. This is very laborious, consumes considerable time, and is expensive.

So far as I am aware, no machine has ever been devised for automatically assembling the heddles on the cross'bars ofxa heddleframe. 1 v

The object, therefore, of my invention is to provide such a machine. Y 7

A further object is to provide such a machine which shall be compact and simple in its organization, and positive and re-- liable in operation.

With these objects in view, the invention resides, generally stated, in a machine comprising the combination of means for sup porting the heddle frame-bars on which the heddles are to be strung, a reservoir or hopper for holding a supply of heddles, rotating carriers disposed beneath said hopper and in the line of fall or descent of said heddles after dischargetherefrom, for conveying said heddles to said heddle framebars, means for feeding the heddles, successively, from saidhopper in timed relation with the movement of said carriers,

and means cooperating with said carriers for preventing accidental disengagement of said heddles therefrom and for presenting the same with the eyes thereof in proper position to be engaged by said frame-bars. The invention also resides in certain novel structural features going to make up the ultimate perfection of the machine as an entirety; such, for instance, as a peculiar form of cam for elevating the hopper feedslide and for giving the same a. shaking or jarring movement while at its highest oint of elevation, so as to cause'the hedd e to drop therefrom onto the rotary carriers.

The accompanying drawings, forming part of my specification, clearly disclose an exemplary form of embodiment of the of the arrows, showing the position of the parts when the slide is at its lowest point;

Fig. 4 is a fragmentary sectional view, taken on the sameline 3-3 of Fig. 1, showing the position of the parts When the slide is at itshighest point; and

Figs. 5 and 6 are fragmentary detail views showing more particularly the spring ten sion means cooperating with the rotating carrier (shown in dotted lines), the latter being shown in said figures at different stages in its rotation and as having moved Specification of Letters Patent, Patent d O t 12 1920; I 7 Application filed May 14., 1920.

the heddle from theposition shown in Fig.

5 to that shown in Fig. 6.

7 Reference may now be had, in detail, to the drawings:

The working parts of my machine may preferably be disposed or supported upon a pedestal 1, desirably hollow, for the sake of lightness, and provided in its front wall, at the top thereof, with an opening 5 extending substantially from side to side of said wall.

Supported at the top of the pedestal, above said opening5, is an elongatedhopper or reservoir 6 of the usual transverse V-form, as shown in Fig. 3.

Disposed against the inner surface of the front inclined wall of said hopper, and ex tending the length thereof, is a metallic strip oriplate 7 bent, at its lower end, as

shown at\ 8, said bent portion projecting into the exit end of said hopper, so as to obstruct, to a certain extent, passage therethrough, and permit passage of one heddle,

on lly, at one time. r

e bottom 9 of the hopper is,.as shown I a 11 is a vertically disposed and vertically is of such a width, or is so positioned relative to the slide 12, that the latter, when at its lowest point of movement, is below the top of the gate, as seen in Fig. 3, and, when at its highest point of movement, theinclined top 13 thereof is flush with the beveled top 15 of the gate, as seen in Fig. 4. It will be noted hat the slide 12 is dis posed between thebase wall 11 of the hopper and said gate 14, and is guided in its reciprocation therebetween.

Disposed in cut-away portions in the lower part of the slide 12, which cut-away portions register with correesponding cut-away 7 portions in the gate14, are rollers 16,16

revolubly mounted on axles 17, 17 supported by said slide.

Projecting through the side walls of the pedestal 1, near the top thereof, is a revoluble shaft18 carrying fast on one exteriorly projecting end a gear-wheel 19 meshing with a worm20 on a counter-shaft 21 suitably supported in bea'rings22, 22 carried by the pedestall, Fast on said shaft21, at one end thereof, is a belt-wheel or drum 23, over which passes an endless belt (not shown) driven'from a power wheel or pulley (not shown) .Fast on said shaft 18 and frictionally engaging the rollers 16, 16 are cams 24, 24, provided, at their highest points with successive scallops, or curved grooves, 25, 25, at

,,least two of said grooves being provided for each ofsaid highest points of each cam, for

a purpose presently appearing.

Also fast on said shaft 18, at points thereon in proximity to theupper ends of the Q heddle-bars A, A, are carrier-rolls 26,26,

each of which is, as shown, peculiarly formed; 11. 6., it has a plurality of peripherally-cut away portions, each of which provides said roll, with a peripheral flat surface .27, a curved recess 28 at one end of-said flat surface, and a wall'29 disposed substantially at right angles to the plane of said fiat-surface and radially disposed with reference to the axis of rotation of said roll. As shown in .Fig. 1, there are two parallel series of said cut-away POI'tlOIlS.

Each of said rolls is also provided with two peripheral, circumferential grooves 30, 30, concentric with the axis of rotationof said roll. The tops of i the heddle-bars A, A; are'positioned 'in one of said. grooves 30,.prefei'ably the outer one;

and upper and lower leaf-springs 31, 32,

respectively, are disposed in the other groove.

As shown, the leaf spring 32 is relatively long, and is supported "at both ends in brackets 33, one of which is adj'ustably secured to the front wall of the pedestal 1 by a set-screw passing through a longi tudinally-extend1ng slot 35 in the bracket,

and the other of which is adjustably secured -to the under surface of the topof the machine by a similar set-screw v 34 passing through a, like slot in this bracket. The

brackets 33,33 are, as shown in Fig. 3,

adjacent the lower ends of the hopper 6 Each of said springs 31 has a lower, longitudinally curved portion 37 conforming to the curvature of the spring 32 and bearing thereon. l 7

In operation, the shaft 18 will be revolved by reason of its geared connections with the shaft 21 driven from the belt-wheel 23. Through the cams 24 fast on the revolving shaft 18, the slide 12 will be raised, thus carrying with it the heddle WlIB B resting thereon, until the highest point ofthe cam is reached, at which time the lower edge of the inclined'top 13 of the slide 12-iwill be substantially flush with the top of the gate 14, whereupon the shallow curved grooves.

25, 25 will give the slide 12 a jarring motion to insure the heddle-wire 13' passing therefrom over the gate 14, whence it falls onto one of the arcuate or sector-shaped peripheral portions of the .rolls 26'. At this point in the-operation, the position'of the moving parts will be as shown in Fig.4. The

heddle-wire B rests upon this curved portion 26 of the rolls 26, 26,'and, in the 'continued movement of the rolls, the inclined straight peripheral surface .27- of said rolls moves beneath said heddlerand out lofqcontact therewith, leaving the same supported upon the springs 32, as'shown in Fig. 6.

Then, as the rolls continue theirrrevolution, 1 the wall 29 rides into: contact'with the bed dle-wire B and pushesthe same betweenthe springs 27, 32, as shown in Fig. 5., thus separating said springs slightly, and calrrying' the heddle-wire around until the top of the heddle-bars A, A passes through the end eyes of the heddle-wire, whereupon the latterfalls by gravity down the verticallyin Fig. 1.

- disposed heddle frame-bars A, A, asshown rier-rolls 26, 26, so that the upper ends of said bars will be in the path of movement of the heddles A as they are carried around by said rolls and the lateral eyes I), b of the heddles engaged with said upper ends of the frame-bars at a predetermined period in the rotation of said carrier-rolls. To this end, the front wall of the pedestal 1 carries, toward its lower end,two projections or bosses 2, 2, and each frame-bar A is provided, toward one end, with a longitudinally-extendingslot 4, through which a set-screw 3 may pass for adjustably securing the bar A to said boss.

While I have described, with great particularity, a concrete embodiment of my invention, it is to be understood that the same is capable of modification, especially in detail, without departing from the spirit of the invention, or necessarily sacrificing any of its advantages. -All such changes as come within. the scope of the appended claims are within the purview of the in vention. 7
